Abstract: Techniques for leveraging downlink bandwidth when uplink bandwidth is limited are provided. An image is captured at an edged device, the image including at least one face of a person, the image captured at a first resolution. The image is stored at the first resolution in the edge device. The image is converted to a second resolution, the second resolution being lower than the first resolution. The converted image is sent to a backend facial recognition system. A set of candidate facial recognition matches is received. Facial recognition is performed at the edge device based on the stored image captured at the first resolution and the set of candidate facial recognition matches.
